Node Service

Get Alfresco Repository node metadata and create nodes with metadata. This service cannot be used to create nodes with content.

Methods

getNodeMetadata(nodeId: string): Observable

Get the metadata and type for passed in node ID (e.g. 3062d73b-fe47-4040-89d2-79efae63869c):

import { NodeService } from 'ng2-activiti-form';

export class SomePageComponent implements OnInit {

  constructor(private nodeService: NodeService) {
  }

  ngOnInit() {
    // Get the node reference from somewhere...
    const nodeId = '3062d73b-fe47-4040-89d2-79efae63869c';

    this.nodeService.getNodeMetadata(nodeId).subscribe(data => {
        const nodeMetadata = data.metadata;
        const nodeType = data.nodeType;
      },
      this.handleError);
  }

  private handleError(err: any): any {
    console.log('Error: ', err);
  }

The metadata response doesn't include the cm:auditable properties (i.e. created, creator, modified, modifier, last access) or the name of the node (i.e. cm:name).

The metadata response looks like in this example:

author: "Martin"
description: "Installation guide for Alfresco 3.3 on Linux"
lastThumbnailModification: "doclib:1505900632400"
title: "Install 3.3 Linux"
versionLabel: "1.0"
versionType: "MAJOR"

Note that the properties are missing namespace prefix. The nodeType response will be returned with namespace prefix, such as cm:content.

Executing this method on a folder node returns no metadata, just the type.

createNode(name: string, nodeType: string, properties: any, path: string): Observable

Creates a node in the Alfresco Repository with passed in name, nodeType, and metadata properties. It will be created in the folder path that is passed in.

import { NodeService } from 'ng2-activiti-form';

export class SomePageComponent implements OnInit {

  constructor(private nodeService: NodeService) {
  }

  ngOnInit() {
    const nodePath = '/Guest Home';
    const nodeName = 'someFolder';
    const nodeType = 'cm:folder';
    const properties = {
      'cm:title': 'Some title',
      'cm:description': 'Some description'
    }
    this.nodeService.createNode(nodeName, nodeType, properties, nodePath).subscribe(nodeInfo => {
        console.log('Node info: ', nodeInfo);
      },
      this.handleError);
  }

  private handleError(err: any): any {
    console.log('Error: ', err);
  }

Note that the path property should not include /Company Home.

The response includes all metadata about the new node:

entry: 
    aspectNames: (2) ["cm:titled", "cm:auditable"]
    createdAt: Mon Nov 06 2017 13:04:49 GMT+0000 (GMT) {}
    createdByUser: {id: "admin@app.activiti.com", displayName: "ADF User"}
    id: "1ab71bb1-d67f-4147-95f6-b5801830ca08"
    isFile: false
    isFolder: true
    modifiedAt: Mon Nov 06 2017 13:04:49 GMT+0000 (GMT) {}
    modifiedByUser: {id: "admin@app.activiti.com", displayName: "ADF User"}
    name: "someFolder"
    nodeType: "cm:folder"
    parentId: "a29b5fe3-81f6-46a7-9bed-6a53620acb32"
    properties: {cm:title: "Some title", cm:description: "Some description"}

createNodeMetadata(nodeType: string, nameSpace: any, data: any, path: string, name?: string): Observable

This is a convenience method if your property list is missing namespace prefix for property names. The namespace prefix can then be supplied separately and this method will prepend it automatically. This method calls the createNode method internally:

import { NodeService } from 'ng2-activiti-form';

export class SomePageComponent implements OnInit {

  constructor(private nodeService: NodeService) {
  }

  ngOnInit() {
    const nodePath = '/Guest Home';
    const nodeName = 'someFolder';
    const nodeType = 'cm:folder';
    const propNamespacePrefix = 'cm';
    const properties = {
      'title': 'Some title',
      'description': 'Some description'
    }
    this.nodeService.createNodeMetadata(nodeType, propNamespacePrefix, properties, nodePath, nodeName).subscribe(nodeInfo => {
        console.log('Node info: ', nodeInfo);
      },
      this.handleError);
  }

  private handleError(err: any): any {
    console.log('Error: ', err);
  }

See the createNode method for information about the response object.
